Abstract
Practical recommendations are given on the operation of wheeled tractors with units of variable mass (trailed and / or semi-trailer tanks) without constructive modernization of the unit itself. Since during the performance of transport work on a wheeled tractor, there are longitudinal vibrations that occur when a fluid oscillates in a tank, it becomes necessary to combat them. Thus, the most popular tie-go-coupling devices that are used when coupling agricultural units are considered. It is highlighted that the priority is a hydroficated hook, which constructively consists of a damping mechanism. It is also noted that among the most desirable transmissions that modern wheeled tractors can be equipped with are infinitely variable double-flow and hydrovolume-mechanical ones. The main advantage of which, in contrast to transmissions of analogs, is the presence of a hydraulic link, with the help of which the mechanical oscillations of a unit of variable mass are reduced, coming in through transmission units. Since, for the tractor industry, the diesel engine of the internal combustion engine still remains the main driving power unit, an electronic fuel management system is presented, which differs from the similar ones in the control algorithm. The main video window of which is the method of microcontroller speed control of the crankshaft, which is based on the fact that to achieve an equilibrium (stable) mode of operation, the required position of the fuel rail is set, which positively depends on the position of the fuel supply control body and negatively on the current crankshaft rotation frequency making any design changes to the fuel equipment, allows to improve the performance of the diesel.
